Martí Gich has participated in a study published today in Science

Written by JAGS on May 17, 2013. Posted in New publications, News.

In this study, authors demonstrate the formation of oriented piezoelectrically active α-quartz thin films directly on silicon. Films are prepared by dip-coating from alcohol/ water solutions of soluble silicic acid precursors plus surfactant or block copolymer structure-directing agents. Solvent evaporation drives the self-assembly of amorphous silica films composed of ordered arrays of pores. An appropriate thermal treatment results on epitaxial quartz films.

We congratulate the authors and specially our group member Martí Gich. You can read the full article

PENGFEI and MULING PRESENTED THEIR PhD PROJECTS

Written by JAGS on May 14, 2013. Posted in General News.

Pengfei and Muling participated as speakers in the 1st Scietific Meeting of ICMAB-ICN-CIN2 students. Pengefei with a presentation entitled Porous Carbon / Bismuth Nanoparticles Composites for Sensitive Heavy Metals Detection and Muling with one under the tiltle Preparation and Characterization of Bacterial Cellulose Films. They both did a great job.

The rest of the group also attended and were very active putting forward lots of questions to young speakers. If you want to know more
